Safe Cell NBC filterNuclear, Biological, and Chemical protection
The ASR-200-AV-NBC Safe Cell is a positive pressure nuclear, biological, and chemical air filtration system.

It features an internal automatic switching power supply that will automatically switch to drawing power from a user supplied 12 volt battery if the power grid goes down. When the power comes back on, the power supply automatically switches back to AC power and recharges the battery.

The Safe Cell has been designed from the ground up to overpressure a protected space so that the only way for outside air to enter your shelter is through the filter.

What's included with this item

ASR-200-AV-NBC Safe Cell - everything includedThe Safe Cell comes with everything necessary to pull it from the boxes and install it in a safe room. If your room is sealed up, you will also need an overpressure valve. If you are installing it in a blast resistant shelter, you should also install blast valves. Please see our complete blast protected NBC air filtration system for a package deal made for underground shelters.

One AC and DC capable Safe Cell with a complete filter bank that includes the two pre-filters, a nuclear grade HEPA particulate filter, and a warfare gas carbon adsorber.
Two wall mount brackets, two quick release clamps, two star nuts, and four lag screws.
One AC and one DC power cord.
One 60 inch chemical resistant flexible air intake hose.
One wall mount flange and gasket for the hose.
One hard copy of the installation and operation manual.


Optional equipment
The Safe Cell includes everything necessary to install and operate. When installed in an air tight protected space like a safe room, an overpressure valve on the outflow vent is recommended. When installed in a blast resistant shelter, blast valves are recommended. The complete system also include two blast valves, an overpressure valve, and a backup hand pump.

  • Emergency backup hand pump or the emergency backup hand crank - for long term power outages

  • Blast valves - protect against the pressure and vacuum of nearby detonations

  • Overpressure valve - provides a metered resistance on the outflow side to help the Safe Cell create and maintain overpressure

  • Blast resistant steel ventilation pipes - easily installed pipes that bolt on to the outside of the shelter

  • Automatic ventilation blower - this blower uses the same plumbing as the Safe Cell to provide unfiltered ventilation of a shelter when there are no airborne threats

  • Replacement filters - every Safe Cell should have a reload of filter elements at hand
